About this gameFull description from Steam
The world collapsed after a nuclear war. Cities were reduced to ruins, roads vanished beneath the ash, and the territory of the former United States was divided into scorched, deadly sectors. From the ruins of the old world emerged D.E.C.A.Y. - the Department of Environmental Control and Yield. Officially, it is an agency responsible for distributing what remains of vital supplies. In reality, it is a cynical, ruthless, and final force struggling to maintain control over a dying planet. You are the operator of a remote bunker designated “Facility 16”. You signed a contract with the organization for exactly 365 days. One year of autonomous service under total isolation and extreme risk in exchange for a single reward - absolute freedom. Provided, of course, that you survive long enough to receive your final settlement. Key Features: Your bunker is your fortress and your workplace. Maintain life-support systems, repair equipment at workbenches, calibrate the neuro-sensory modules of your personal PDA, and keep track of your supplies. Every new 24-hour cycle changes the balance of threats and available resources on the surface. The sky is under your control. Your primary duty is to maintain the A.C.C.S. “Atlas” surface network. These massive installations sustain a radiation and thermal shield over the region, preventing the sun from scorching the surface. Monitor the power grid from the bunker’s main terminal, venture outside, locate expensive nuclear batteries, and perform “hot” replacements. Remember: the shutdown of even a single node immediately redistributes the load, causing neighboring Atlas units to drain several times faster. A loyal mechanical companion. You have access to a specialized search bot capable of accompanying you on the surface and assisting during dangerous expeditions. Only its built-in sensors and manipulators can detect emissions from the rifts, scan them, and safely extract valuable post-nuclear modifiers. Protect the bot while it works - without it, you may return to the bunker empty-handed. The treasures and curses of the rifts. The crystalline modifiers recovered by your bot provide powerful advantages, but many also carry dangerous side effects. Install a stable “Amber Heart” in your suit to slightly increase your health, or risk using the blazing “Death Stone,” capable of devastating your body’s protective systems. You can also surrender the dangerous mineral to the Department, which uses its destructive energy to manufacture heavy special-purpose ammunition. Wasteland politics. Not everyone agrees with the Department’s methods. Beyond the sealed bunker doors, you will face raiders, feral mutants, and soldiers of the high-tech faction known as “Legacy.” When their heavily armored enforcers, the “Judges,” arrive in your sector, you will need to use your entire tactical arsenal to survive. Hardcore VR immersion. Experience realistic environmental interaction and authentic shooting physics. The game features 32 weapons - from assault and sniper rifles to pistols, heavy fire axes, and baseball bats. Discover deeply detailed weapon mechanics: for example, the heavy M88 “Hunter” carbine requires you to manually rotate the bolt handle and pull it back after every powerful shot. As you complete more directives, one thing becomes increasingly clear: the orders issued by your superiors do not always match the reality on the ground. Eventually, you will have to decide whose contracts to accept and what order truly means to you. You have no squad. No permanent support. No safe zones. There is only you... Your search bot... Your bunker... And the countdown to freedom...
